Apollo Environmental Control Unit Shutoff Valve, measuring approximately 5 x 6 x 3, bearing parts labels affixed to three separate sections, reading: “Valve Shutoff, Part 828070-6-1, Serial 125-114, Order NAS-9-150, NASA 004000125110,” “Motor A.C. Aircraft, Part 821140-1-1, Serial 85-123, Order NAS-9-150, NASA 004000085123,” and “Actuator Rotary, Part 820370-2-2, Serial 115-137, Order NAS-9-150, 004000225137.” In fine condition. The Apollo Command Module Spacecraft Environmental Control Unit (ECU) shutoff valve provided a means of isolating the astronaut's A7L spacesuit suit circuit from the cabin air circulation system when the spacesuit was connected to the ECU. This was done to prevent inducting cabin gases into the suit circuit in the event the cabin gases became contaminated.
